Complications and retrieval characteristics of Celect Platinum inferior vena cava filters.

BACKGROUND: The purpose of this study was to retrospectively assess the retrieval characteristics and rate of filter-related complications associated with use of the Celect Platinum (Cook Medical, Bloomington, Ind) inferior vena cava filter (IVCF).

METHODS: A single-center, retrospective review was conducted to identify patients who received a Celect Platinum IVCF between June 2013 and February 2016. The patients' charts and imaging records (computed tomography [CT] and cavography) associated with filter placement, follow-up, and filter retrieval procedures were assessed for attempted and successful retrieval rates and filter-related complications.

RESULTS: During the review period, 562 Celect Platinum filters were placed in 556 patients. Outcome and evaluable imaging data (CT and cavography) were available from 335 patients, with median CT follow-up time of 45 days (average, 126 days) and median cavography follow-up time of 90 days (average, 102 days). IVCF leg perforation of the inferior vena cava wall >3 mm was identified in 65 cases (19.4%) on follow-up imaging (64 cases). In addition, filter tilt >15 degrees was identified in 4 filters (1.2%), filter migration >2 cm in 1 filter (0.3%), and occlusive filter or inferior vena cava or iliac vein thrombus in 11 filters; no filter fracture was observed. One case of breakthrough pulmonary embolism and two additional indeterminate cases were identified on follow-up CT pulmonary angiography (2.6%-7.7%). Retrieval was successful in 155 of 155 patients (median indwell time, 90 days; range, 1-445 days); an advanced retrieval technique was used in 11 retrievals.

CONCLUSIONS: The outcomes for the Celect Platinum filter were comparable to those previously reported for the first-generation Celect filter in all categories assessed.
